upper extremity axillary loop grafts: an opportunity in hemodialysis access

چکیده
background dialysis vascular access complications are considered as significant causes of morbidity in chronic hemodialysis patients. objectives the aim of the present study was a comparison of axillary loop and straight grafts patency and its complications in hemodialysis access. patients and methods in this cohort study conducted at shahid beheshti medical university, 77 patients who underwent placement of loop or straight access grafts were included. demographics, primary and secondary patency rates and complications like thrombosis, infection, bleeding, steal syndrome and other complications were compared in these two groups. the collected data was analyzed by chi-square test, t-test, and logistic regression. results primary patency rate in straight and loop groups after 1 month were 88.9% and 92.3% respectively (p = 0.721), and after 24 months were 31% and 55.5% respectively (p = 0.058). secondary patency rate in straight and loop groups after 3 months were 75.6% and 92.3% respectively (p = 0.189), and after 24 months were 37.9% and 66.7% respectively (p = 0.044). the frequency of complications were the same among two methods of graft replacement and mal incidence of thrombosis, infection, delayed infection, pseudoaneurysm formation and steal syndrome occurrence ultimate graft failure and venous hypertension were not significantly different (p > 0.05). conclusions polytetrafluorethylene (ptfe) vascular graft seems to be an appropriate vascular access and is a promising alternative when upper extremity arteriovenous fistulas cannot be constructed. additionally, there was no significant difference between the two groups for complications and early patency, but late patency was improved in loop group. more study is necessary for a conclusive assessment.

Thrombotic and infectious complications are frequent causes of hemodialysis vascular access failure and contribute considerably to the cost of care for chronic hemodialysis patients. Although there is clear indication for removal of patent grafts in unresolved bacteremia, there are no guidelines for the management of clotted nonfunctioning grafts. To evaluate for the existence and clinical rele...

Arterioarterial Prosthetic Loop as an Alternative Approach for Hemodialysis Access
In the present study, we performed an arterioarterial prosthetic loop (AAPL) between the femoral artery and deep femoral artery as a new access in patients who did not have adequate vascular conditions for creating an arteriovenous fistula or graft.Between April 2005 and June 2014, 18 patients received AAPL as a vascular access. During the procedure, a polytetrafluoroethylene graft was anastomo...
